zen. of tlieUnited: States7v` iund` residing at Chicago, `county of, Cook, endStzitefo lli-` nois, have invented .certain new and useful lin rovernents in a Grain Door of Whichthe P i following is fulhclear, andere@ desCiption;` reference being hed tothe accompanying' drawings, Which torina part of this specifies-tion.

. My present invention relates to grain doorsA for railway freight cars?A ond has reference more particularly tothe permanent type off grain doorg one object being to improve the 1 construction and. increase the eiiiciency. and

utility et doors of this type.

A further` object resides in the fact that the door parte or sections While possessingi the characteristic'of niexiinuin strengthiind rigidity .to

:i slideiviiy l5 iler the hurl@ Whose lower end col-:iets with :in ibutiiienjt lion the door ly 'wv it insiy he sivun from its closed position open position it occupies in Figure drawings. This movement is steedied by ine-sns oi vertically disposed' rod i9 `eri-- tending' from vthe tioorfto te side plate 8, and ivliichisa oit' course7 spaced 'dit ,is recessed to provide` to holdfthe ltterclosed. The door section 'A pivoteil thedoori" imnie shown of the away from the door post .11 to provide a clearance tor the passage not only or" the door section A- but also 'the intermediate grain door section B in their yopening' and closing movements.

When in open pQsition, the section B is carried in a slideway, mounted on the siding, and which in the present instance embodies the upper and lower siideway members 20, 2O arranged so as to permit the scction to have longitudinalsliding movement from its open position shown in Figure 7 to its closed position in the doorway opening (Figure l). ln this position it is superimposed uponv the lower secton A, and it will be observed from an inspection of Figure 3 that the meeting edges of these sections are jointed or lapped, iirst,to provide a guideway 2l for the section YB duringits movement, and, second, to prevent` leakage past this joint. lt will also be noted in this connection that the inner side face of the 'forward door post l2 1s also cut away to provide a full seat'QQ for the reception of the front edge portions of both oi these sections. It desired, a metal plate 23 may be secured against the `inner face of the post to protect the shoulder 24 against wear from the grain scoop ropes.` `With lthe yobject in view ot obviating leakage or grain past the rear edge yportions oi' the sections A and B, the iatter may desirably be provided with the wedges 25 and 26, respectively, whereby in the iinal closing movement oi' the sections `these wedges co-act with the rod 1,9 to force said .rear edge portions inwardly into a tight engagement with the doorpost il, as will be understood.

.The slideway members 2O terminate short of' the doorway opening, thereby leaving l suihcient'space for'tlie door section A to c occupy when raised into its elevated open opening.

position against the front edgeportion of the'intermediate door section B, whose rear edge portion in turn abuts the stop 27. A latch Q8 pivotally mounted on the upper slideway member 20 is positioned to engage arr abutment 29 on the door section A so as to maintain it in its open position, and when so maintained obviously it holds the inter- 'incdiate door section B against involuntary movement in a direction toward the doorway This door section B is provided with rearward extensions 30, 30 which at all times slidably engage in the slideway, hence the guiding influence orn the latter is always maintained and any possibility of the pilierage or unwarranted withdrawal oit this section is thereby eliminated.

drawings, the upper section C is hingedly mounted on the side plate 3', or any other suitable overhead doorway 'frame member, to swing from its raised open position, indi- As will be seen from an 'inspection of thek cated in dotted lines in Figure 3, to its closed position disclosed in full lines in said ligure,

the hinges being denoted by the reference character 3l, 3l. i rlhe section is maintained in its elevated position by means otany suitable latchingdevice, such as that indicated at 32, and its lower meeting edge poris normally seated for the purpose of holding both door sections B and C in closed position. l/Vhen this element 34 is thus raised, both doors may be moved to their open posi tions, and when so moved the section. A may then in turn be swung to open position on its pivot. lt should be observed that the vertical rod is positioned so as not to interfere with lthe movement of door section C. It desired,` gravity locking members 36 and 37 may additionally be employed for the grain door sections A and B, respectively, the forg mer for locking the section A when used separately for coal and both when these sections are employed ingroup Jform without the hinged section C. Furthermore, the lower section when in raised position is prefera/bly arranged so as to leave a space between its bottom edge and the floor to clear any pieces of coal that may have been left in the car.

i'fissuming the door is in open position, it will he obvious from the foregoing description that upon the release of the latch 28 the section A may be swung downwardly on its pivot 18 into its closed position as shown in Figure 7, whereupon sliding movement is imparted to the section B longitudinally of the slideway andthe guideway in the upper edge of the section A to bring it, in turn, into its operative closing relation with the doorway opening. Incident to the completion ot these movements, the locking the sections to positively maintain their operative relation which latter is rendered more effective by the lapped joints and the wedging action afforded by the co-operation between wedges 25, 26 and the rod 19. Upon release of the latch 32, the upper Section C drops into place, and in its final closing movement the bent end 34 of the locking element 3d is cammed up and falls into its seath `When thusseated, element 34 locks both sections B and C independently ot the members 36 and 37, and obviously the lower section is immovable with the others superimposed upon it. inasmuch as ing.I of.l parts to1 the doorposts,y as is. neces-y liet-,31.3

thefsteps italien in ,the opening @t the door sections are exactly the `reverse oit those take-n in their closing, no 'further eiiplanaV tion is dee-ined necessary. i

lt will be apparent ythat. destructive nails'arily i done with temporary grain doors, i is wholly obviatedrr This customary'practice, apartpfroni occasioning damage to the posts,

is .wasteful in the extremaand obviously sol -f g in view y ot the constant scraping of `these tein'porarydoors after'a single trip. My

door, comprising as it does a. series of mo-y bile sections, eachhaving its appointed place of-storage when not inuse, is veasily handled yand yiii the shortestpossible time at grain chutesandelevators. It is simple in construction, possesses maximum strength andrigidly vprevents leakage of grain past contacting surfaces,is tool-proof and easily y installed, and the parts are 'readily fabricated and asreadily replaced should that become necesszfiry-,v ,Other advantages,it Vis believed, will beapparent to others skilled inth-is art.. i A
